摘　　要：在聚氨酯硬泡阻燃配方中加入纳米金属氧化物,利用氧指数分析仪、热重分析仪、微型量热仪和热重红外联用,研究了纳米氧化锌、纳米二氧化钛、纳米三氧化二铁这3种纳米金属氧化物对阻燃改性聚氨酯硬质泡沫的热分解过程和阻燃性能的影响。结果表明,金属纳米氧化物的加入可以减少材料热解过程中可燃性物质的含量,促进不燃性物质的生成,提高残碳量,降低材料的燃烧性能。Several mental oxide nanocrystallines were used in flame retardant rigid polyurethane foam（ PUF）.The influences of nano zinc oxide,nano titanium dioxide,nano ferric oxide on flame retandant properties and the thermal decomposition process of rigid PUF were investigated by LOI,TGA,MCC and TGA-FTIR. The results showed that the metal oxide nanocrystallines could increase the formation of incombustible matter,decrease the content of combustible materials and increase quantities of carbon residue,while reducing the materials combustion properties.
